Description

Technical Field

[0001] The utility model relates to the technical field of nutrient solution preparation, in particular to a nutrient solution preparation device. Background Art

[0002] Nutrient solution is a new type of nutrient solution synthesized by biological fermentation, chemical chelation, physical activation and other processes using environmental biological ecological symbiosis technology and mycorrhizal symbiosis principles. Plant nutrient solution is generally a multi-component composite nutrient in water form. Its concentration is not as high as that of solid fertilizer, and it has fewer impurities and is easy for plants to absorb. Nutrient solution is the main source of mineral nutrients and water required for soilless crops. Its composition should contain all the ingredients required by crops, such as large and medium elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and trace elements such as iron, manganese, boron fertilizer, zinc, and copper. When mixing the nutrient solution, a mixing device is required.

[0003] At present, most of the existing nutrient solution mixing devices use fixed mixing tanks for stirring. However, when the stirring blades rotate unidirectionally, the stirring efficiency is not high, resulting in low efficiency in nutrient solution mixing and affecting the mixing uniformity of the nutrient solution. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a nutrient solution mixing device to solve the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a nutrient solution mixing device comprises a mixing tank, a feeding pipe is provided at the top of the mixing tank, a discharging pipe is provided at the bottom of the mixing tank, a stirring mechanism extending to the outside is provided throughout the interior of the mixing tank, the stirring mechanism comprises a driving motor and a rotating shaft installed on a mounting plate on one side of the mixing tank, one side of the interior of the mixing tank is rotatably connected to an inner stirring frame through a bearing, the rotating shaft is rotatably connected to the other side of the interior of the mixing tank through a bearing, an outer stirring frame located outside the inner stirring frame is provided on the surface of the rotating shaft, a No. 1 pulley group is sleeved on the outer surface of the output end of the driving motor and the outer surface of the rotating shaft, a support shaft is rotatably connected to the vertical plate at the front end of the mixing tank through a bearing, the outer surface of the output end of the driving motor and the outer surface of the support shaft are sleeved with a gear group, and the outer surface of the support shaft and the outer surface of the inner stirring frame are sleeved with a No. 2 pulley group.

[0006] Preferably, a scraping mechanism extending to the inside of the outer stirring frame is arranged inside the rotating shaft, and the scraping mechanism is composed of an electric push rod, a guide plate, a slide plate, a linkage plate and a scraping frame.

[0007] Preferably, an electric push rod is installed on one side inside the rotating shaft, and one side of the electric push rod is connected to a guide plate that forms a sliding structure with the rotating shaft.

[0008] Preferably, a slide plate is slidably connected to the inside of one end of the outer stirring frame, and a linkage plate is rotatably connected between the slide plate and the guide plate via a hinge seat.

[0009] Preferably, a cleaning frame which forms a sliding structure with the outer stirring frame is provided at one end of the slide plate, and the cleaning frame consists of a horizontal plate and a vertical rod.

[0010] In summary, the utility model mainly has the following beneficial effects:

[0011] 1. When the existing mixing device is in use, the stirring blade rotates in one direction, and its stirring efficiency is not high, which leads to low efficiency in mixing the nutrient solution and affects the mixing uniformity of the nutrient solution. The utility model is provided with a stirring mechanism. When the driving motor is working, the output end of the driving motor drives the rotating shaft and the outer stirring frame to rotate under the action of the No. 1 pulley group. Since the outer surface of the output end of the driving motor and the outer surface of the supporting shaft are sleeved with a gear group, and the inner stirring frame and the supporting shaft are linked by the No. 2 pulley group, the inner stirring frame rotates in the opposite direction to the outer stirring frame, which can help improve the efficiency of mixing the nutrient solution and improve the mixing uniformity.

[0012] 2. After the mixing is completed, the existing mixing device is not convenient for cleaning the mixing barrel, resulting in nutrient solution adhering to the inner wall, causing waste and being not conducive to subsequent reuse. The utility model is provided with a scraping mechanism. Since the slide plate and the guide plate are linked by the linkage plate, when the electric push rod is working and extending, the guide plate slides horizontally and the slide plate slides vertically, so that the scraping frame contacts the inner wall of the mixing tank. When the rotating shaft rotates, the scraping frame can be used to scrape the inner wall of the mixing tank, thereby reducing the waste of resources and facilitating subsequent reuse.
